Anti-corrosion paint capable of coating with rust

technical field [0001] The invention relates to an anticorrosion coating which can be applied without derusting. Background technique [0002] When traditional coatings are applied on the steel surface, it is required to completely remove rust. This is a very heavy work, which not only consumes a lot of man-hours, but also increases costs, because the existence of rust has a great impact on the quality of the coating. It is estimated that the general construction cost is 5 times of the coating cost, and the construction cost of marine equipment can be up to 10 times. According to reports, the distribution ratio of steel plate coating costs is: surface treatment accounts for 42%, construction accounts for 30%, and paint accounts for 19%. [0003] For some large-scale projects, such as bridges, ships, offshore oil production facilities, etc., due to the long construction period, the pre-painted primer is often damaged and rusted again during the construction process.
